LINER FOR CENTRIFUGAL LIQUID-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 792,434, dated June 13, 1905.

Application filed September 26, 1904. Serial No. 225,875.

To all 1071,0121, itvnmy concern.-

Be it known that I, \VILBUR IV. MARSH, a citizen of the United States of America, and a resident of \Vaterloo, Blackhawk county,, Iowa, have invented certain new and useful Improvements in Liners for Centrifugal Liquid-Separators, of which the following is a specification.

My invention relates to liners for centrifugal liquid-separators; and the object of my invention is to furnish a liner consisting of concentric separating devices each of which is built up of aseries of separating-plates mounted on radial uprights, said uprights being separable from each other, but linked together in such a manner as to permit of the opening away from each other of the different parts after removal from the bowl for the purpose of facilitating the operation of cleaning or repairs. This object I have accomplished by means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figurel isa plan view of my improved type of liner. Fig. 2 is an elevation of the same, a portion being represented as removed along the line mmin Fig. 1; and Fig. 3 is adetached detail view in perspective of two of the outermost series of uprights, showing the manner of placing the separating-plates thereon.

Similar letters refer to similar parts throughout the several views.

In order to obtain the greatest efliciency of separation within the liner of a centrifugal liquid-separator, it is necessary to retard as much as possible the outward radial motion of the liquid as it passes through the liner under the action of centrifugal force. In my improved type of liner I have accomplished this by interposing two series of differentlyinclined plates in the path of the outward moving liquid. Each series of plates is arranged radially about the axis of the bowl and inlet, one series of plates being arranged concentrically about the other.

The outer series of separating-plates f are affixed to the outer series of uprights a and are shown as being inclined outwardly downward. The inner series of separating-plates e are afiixed to the inner series of uprights b and are inclined inwardly downward. In both series the separating plates are attached to one side only of the curved uprights, as shown in Fig. 3, the outer edges of the plates contacting closely with the smooth opposite surfaces of the adjoining uprights when the liner is in the bowl of the separator, thus forming continuous inclined passages for the outflowing liquid. The outer series of uprights a, with their attached plates f, are entirely separated from the inner series of uprights b, with their attached plates 0. Theinner series nests within the outer series concentrically and may be readily removed therefrom. The inner edges of the inner series of uprights 6 connect together by means of the links it, while the outer edges are linked together by means of the links 0. The inner edges of the outer series of uprights a are linked together by means of the links 9, while their outer edges are linked together by means of the links (Z.

Then each series of uprights has been withdrawn from the bowl, the uprights may be widely separated, as shown in Fig. 3, and thus the separating-plates are rendered readily accessible for the purpose of cleaning. Any part of the liner is also easily got at for the purpose of substitution or repairs. In replacing the liner in the bowl the outer series of uprights is compressed into the ring-shaped form shown in Fig. 1 and introduced first, the inner series then being placed in similar manner in the bowl concentric with the outer.

It is not essential that separating-plates inwith the surface of the next adjacent upright being provided With aplurality of separatingforming a series of vertically-disposed radiatplates, substantially as shoWn and described. IO
